Is Marc Steiner smarter than a sixth grader?

Is Marc Steiner smarter than Denise Koch? Can the president of Baltimore's City Council outwit the president of a local college?

Are any of them brainier than your average sixth grader?

Baltimore will find out Saturday when local celebrities play "Are You Smarter Than a Sixth Grader?" for a good cause -- raising money for the Sisters Academy of Baltimore, a tuition-free Catholic middle school for girls from low-income neighborhoods.

It will be just like the television show, except the personalities will compete with real sixth graders in teams. Bravely signed up were radio host Marc Steiner, WJZ-13 anchor Denise Koch, Notre Dame of Maryland University President James Conneely, City Council President Bernard C. "Jack" Young and media critic Bill McCuddy.

And don't think that just because this is for charity anyone will spare the contestants.

Steiner competed then, too. He came in second, so no doubt, he's back this year with something to prove.

The competition ensues Saturday at 7:15 p.m. at Goucher College's Kraushaar Auditorium. Tickets are $25 and available online at www.sistersacademy.org or by calling 410-242-1212. People can also attempt to pick a winning team by pledging $10 in their favorite contestant's name.
